A loaded 15-game Friday Major League Baseball slate delivers prime parlay value. Here are our top combinations for September 18.
Friday Night Major League Baseball Parlay Picks - September 18
Fifteen games on a Friday night in September means playoff races, desperation, and - most importantly for us - parlay value. The books have priced up a massive slate and we've identified three combinations worth targeting tonight. Let's break down the legs, the logic, and where to find the best prices.
Reading the Board: Key Trends on Tonight's Slate
A few themes jump out immediately when scanning tonight's Major League Baseball lines. First, there are several heavy favourites priced into near-unplayable moneyline territory - the Los Angeles Dodgers at -294 (FanDuel) and the Pittsburgh Pirates at -179 (Fanatics) are two examples where the spread offers far better value. Second, the totals market is sitting at cautious levels across most games, with several lines in the 7.5-8.5 range suggesting pitchers' duels or at least modest run environments. Third, a handful of underdog prices look genuinely generous against the implied probabilities, and we'll flag those specifically below.
Value Flags Before the Parlays
- Kansas City Royals +170 (BetRivers) - The Royals have been one of the surprise packages of the 2025 season and +170 against a Pirates squad that is in clear sell-off mode is a number that deserves respect. That's an implied probability of just 37%, which feels too cheap.
- Atlanta Braves -1.5 +146 (FanDuel) - Getting the Braves at plus-money on the run line against an Astros team whose season is winding down is a genuine value opportunity. Atlanta's lineup carries enough firepower to win by multiple runs regularly.
- New York Yankees -1.5 +135 (theScore Bet) - The Yankees are a legitimate postseason contender with a potent offence. Getting them at plus-money on the spread against an Arizona Diamondbacks team managing its own roster heading into the off-season is excellent value.
Parlay 1: The Favourites Run Line Special (+412 combined)
This parlay targets teams with genuine quality at plus-money prices on the run line - meaning we need them to win by two or more runs, but we're getting paid a premium to take that risk.
- Chicago Cubs -1.5 +132 (FanDuel) - Cincinnati is a team going through the motions late in a lost season. The Cubs still have playoff positioning to play for and should have the better arm on the mound in this spot. Plus-money on a Cubs run-line win is strong value.
- Atlanta Braves -1.5 +146 (FanDuel) - As flagged above, this is one of the standout values on the entire board. The Braves' offence is capable of blowing past a Houston rotation that has little to play for.
- New York Yankees -1.5 +135 (theScore Bet) - The Yankees close out this parlay as a third run-line favourite at plus-money. Three teams with genuine quality, all priced as if they're underdogs on the spread. That's where parlay value lives.
Combined odds for this three-leg parlay land around +412, representing a real payout on a modest stake. Each individual leg has genuine merit and the combined price more than compensates for the added variance of run-line requirements.
Parlay 2: Low-Scoring Friday Night Double (+205 combined)
Several games tonight feature pitching matchups and low totals that suggest value on the under. This two-leg combination targets the under in a pair of games where the books have set conservative lines.
- Kansas City Royals @ Pittsburgh Pirates - Under 7.5 +105 (theScore Bet) - A 7.5 total is already modest but this game has the feel of a grind. Pittsburgh's home environment and the matchup profile point toward a low-run affair. Getting plus-money on under 7.5 is genuinely attractive - any number above a push gives profit.
- Toronto Blue Jays @ Texas Rangers - Under 7.5 -102 (BetMGM) - Globe Life Field can play either way but this matchup sets up as a pitcher's duel. A 7.5 total at near even money is a line the books are comfortable with, and so are we. Both teams have motivation to compete but pitching should dominate here.
Combined odds for this two-leg under parlay come in at approximately +205, giving us better than 2-to-1 on a pair of well-reasoned totals picks. This is the lower-variance option on tonight's card.
Parlay 3: The Underdog Moneyline Dart (+369 combined)
When underdog prices look genuinely mispriced, the moneyline parlay becomes the right tool. This combination targets two underdogs whose prices imply probabilities well below what the matchup context suggests.
- Kansas City Royals ML +170 (BetRivers) - We've already flagged this as a value play. +170 implies the Royals win fewer than 4 in 10 times, which undersells a Kansas City club that has genuine talent and will want to close the season strong.
- Boston Red Sox ML +107 (Courtside) - The Rays have their own quality but Boston at plus-money feels like a gift. Fenway South - Tampa Bay's home - has not been the fortress it once was, and the Red Sox have enough offensive talent to take this game. Near-even money for an upset here is excellent value.
Combined odds for this underdog double sit around +369. It is the highest-variance option of our three parlays but the individual values are real and the combined price is handsome.
Tonight's Best Parlay Recap
- Parlay 1 (+412): Cubs -1.5 +132 (FanDuel) + Braves -1.5 +146 (FanDuel) + Yankees -1.5 +135 (theScore Bet)
- Parlay 2 (+205): Royals-Pirates Under 7.5 +105 (theScore Bet) + Blue Jays-Rangers Under 7.5 -102 (BetMGM)
- Parlay 3 (+369): Kansas City Royals ML +170 (BetRivers) + Boston Red Sox ML +107 (Courtside)
Shop the lines before first pitch - several of these prices are moving as sharp money comes in during the afternoon. The run-line values in Parlay 1 are particularly time-sensitive.
